Re: [Networker] Staging just stops... ?

Make sure that none of the save sets sitting in your AFT device have
already expired their retention period. If they have, you will see
messages in your /nsr/logs/daemon.raw that look like:
39078 12/16/08 14:25:14 0 0 2 1 16745 0 scotch.tape.gatech.edu nsrmmdbd
Media DB error: Save set ssid:3691139955 cloneid:1229449336 eligibility
can not be cleared, retention time must be adjusted first
and your nsrstage will look like it just sits there and does nothing.
This is something we just brought to EMC's attention and they have
assigned a BugID # 6787552 to it.
If that is not the case, make sure that your staging policy is set with
a destination pool that matches that to which your mounted tape volume
belongs.

I have a small-ish test environment running 7.4 (Sun version) on Solaris
10 SPARC, with an adv_file device and SDLT320 drive to which it stages.
More than once, I've come in after a weekend (as I did today) to find that
the stage target tape is marked appendable, 47% full (eg., today) and yet
staging has just stopped with the alert "Waiting for more available space
on filesystem '/dbu/_AF_readonly'. Sure enough, /dbu (mount point for the
adv_file device) is 100% used. However, the state policy is set to
70%/50%, 4 hour recover space interval and 3 hour filesystem check
interval and it's been waiting all weekend.
So why has it stopped staging?
There's an nsrstage process out there, but it's just sitting there. Plenty
of space in /tmp, etc., nothing meaningful in the system log beyond what I
already know. Just no activity. trussing the nsrstage process just shows
it sleeping. In the past when this has happened, it's taken killing that
process, labeling a new stage tape and manually kicking it off again.
